NORDEX – A PROFILE Reliable power plants for a clean environment

Economic prosperity, progress and environmental protection –

for Nordex these go hand in hand. Since 1985, we have been

developing increasingly effective wind turbines that help meet the

growing global demand for energy, while reducing the impact on

the environment.

As an internationally expanding company,

Nordex has a footprint in all the growth markets. We deliver

tailor-made, all-round solutions to our customers – from planning

a wind farm, through turnkey installation, to maintenance and

service. The ‘Nordex Academy‘ provides high quality training to

all our staff and guarantees superior expertise as a supplier of

sophisticated products and services.

Our core competence is wind turbines in the multi-megawatt

segment. With the Gamma Generation, we offer different types of

machines for each wind class, using a proven technical platform.

Nordex customers can be sure they’ll have cost-effective solutions

for every site.

03

The Gamma Generation combines modern turbine technology

with know-how and experience from more than a decade

of operation to meet today’s market requirements.

In 2000, Nordex installed the first 2.5 MW series

turbine in the world and has put more than

4,000 machines from this platform on

the grid since then. When we say

that our turbines offer high

quality, mature techno-

logy and dependable

performance even

in extreme locations,

we know what we‘re talk-

ing about.

Nordex continues to develop

Gamma Generation turbines fur-

ther. Yet we remain true to proven

principles, using tried and tested series

engineering and giving top priority to the

dependability of all system components.

We ensure that Nordex wind turbines are capital

goods that generate reliable yields over a period

of at least 20 years.

GAMMA GENERATION Experience puts us one step ahead

Our commitment to continuous development ensures that Nordex

wind turbines offer a high level of technical availability of more than

98 per cent, making it even more worthwhile to invest in a turbine

from the Gamma Generation.

The perfect machine for every type of wind

With its N90/2500, N100/2500, and N117/2400 turbines, the Gamma

Generation achieves high yields at every site. Nordex offers the

N90/2500 for regions with strong winds and the N100/2500 for areas

with mo d- e rate wind conditions. The N117/2400 has been especially

designed for locations with light winds, and, with a rotor diameter of

117 metres, it is highly efficient.

Smart options widen the range of applications

Many good wind locations are in regions with extreme temperatures.

To capitalise on the potential of these locations, Nordex offers the

turbines of the Gamma Generation with a hot-climate package, a cold-

climate package, an efficient ice-detection system on the rotor blade,

and many other useful options to increase yield and facilitate permit-

ting of Nordex turbines. Turbines in the cold-climate design have an

extended operating range and are available for outside temperatures

down to –30 degrees Celsius. Turbines in the hot-climate design have

an extended operating range and are available for outside tempera-

tures up to 45 degrees Celsius. The ice-detection system registers ice

formation on the rotor blades and automatically switches off the wind

turbine generator in order to avoid ice throw. Thanks to the innovative

VERSATILITY Dependable wind yield at every site

06

The Nordex N117/2400 also includes a 141-metre hybrid tower.

measuring system on the rotor blades themselves, the system

rapidly and accurately detects relevant icing on the blades even when

they are not turning and can therefore also automatically release the

turbine again when it is ice-free.

Service – simple, fast and safe

Thanks to the service-friendly design of the turbines, Nordex has

reduced maintenance time to a minimum. Service can be carried out

under a closed roof, regardless of weather conditions. Continuous

work surfaces with sufficient space and light support fast and safe

servicing. All components are directly accessible and can be easily,

safely and inexpensively maintained with the aid of the internal crane.

In addition, reliable turbine operation is supported by low-main-

tenance and maintenance-free components.

Round-the-clock performance checks

To ensure maximum availability, Nordex keeps a constant eye on its

customers‘ wind turbines. In the event of any divergence from normal

operation, Nordex Remote Monitoring immediately intervenes. In add-

ition, the optional Condition Monitoring System checks the state of

wear-critical drivetrain components and, in this way, supports prevent-

ive maintenance.

High in the sky for a better yield

Wind conditions differ from region to region, and wind quality usually

improves in line with altitude. To maximise energy production, Nordex

offers the machines in the Gamma Generation on modular tubular

steel towers or on hybrid towers with heights ranging

from 65 to 141 metres.

07

The turbines of the Gamma Generation are characterised by excellent

control capabilities for maintaining the voltage and stabilising the

frequency of the public grid. They meet all the requirements for the

German system service bonus (known as the “SDL-Bonus”).* Their

fault-ride-through capability enables them to effortlessly bridge dips

in voltage. The Nordex wind farm management system allows the

grid operator to directly control the rated and reactive power of the

wind farm in the grid.

With these features, the turbines are certified for the grids of the most

demanding international markets. They can also be adapted to new

and complex connection requirements, ensuring seamless integration

into the local grid.

Always striving to progress

Our aim is to offer the best power quality on the market. Nordex

intensively tests grid connection technology, both in the field and on

the test bench. This is why our wind turbines have long been

recognised for quality and dependability of supply, equal to or better

than those of conventional power plants.

* The requirements for the SDL-Bonus are regulated in Germany in the System Service Ordinance (SDLWindV). They are among the strictest requirements of grid guidelines in Europe.

Nordex makes sure that the machines of the Gamma Generation always comply with the latest grid requirements.

08

GRID CODE COMPLIANCE Active support for every grid

QUALITY Top-quality engineering – simply routine for us

Thanks to their sophisticated design, the wind turbines of the Gamma

Generation are certified quality products. From the earliest develop-

ment phase Nordex engineers check the stress levels of materials and

components, using advanced computer-aided calculation routines.

These are followed by extensive testing in the Nordex Test Centre and

in the field.

Extreme testing of hardware and software

In the Nordex Test Centre our engineers inspect the components and

systems of the prototypes under simulated wind and weather condi-

tions. By subjecting them to stress exceeding the usual specifications,

such as extreme climate and vibration tests, Nordex ensures that they

meet all quality criteria and that a high-quality and technically mature

product goes into serial production.

Quality-assured rotor blades

Nordex sets especially high standards when it comes to the materials

used for our rotor blades, which can be up to 58 metres in length.

Automated production processes, monitored by the latest measuring

and testing methods, guarantee that each rotor blade works reliably.

Highest industry standards

Nordex manufactures the nacelle and hub module in line pro-

duction, setting the highest standards and delivering optimum

product quality. Many steps in the assembly process are

performed in the protected production hall —

a key prerequisite for the most efficient

installation of turbines

at the wind farm.

09

An eye for detail: in the laboratory Nordex checks the materials for the rotor blade.

Wind locations with rough climates require mature, robust

technology. The IEC-1a-certified N90/2500 has been specifically

designed for these conditions. For any strong-wind site, it is

the first choice for its price – performance ratio.

Nordex has already connected the N90/2500 to the grid hundreds

of times in Europe, Asia and North America.
